Definition

Noun: * Yukon Time: A standard time zone, specifically the time observed at the 135th meridian west of Greenwich (GMT-9). It is the official time used in most of the state of Alaska and the state of Hawaii.

Usage
  • Yukon Time is nine hours behind Coordinated Universal Time (UTC-9).
  • It is the legal standard time for a defined geographic region.
  • Example: "When it is 12:00 noon in New York (Eastern Time), it is 8:00 AM in Anchorage, which observes Yukon Time during standard time periods."
Advanced Usage
  • Historical Context: The name "Yukon Time" originates from its historical association with the Yukon Territory in Canada and regions of Alaska. While still the official time zone designation for most of Alaska, it is now more commonly referred to as Alaska Standard Time (AKST).
  • Daylight Saving Time: Most areas observing this time zone, including Alaska, advance clocks by one hour during summer months, observing Alaska Daylight Time (AKDT, UTC-8). Hawaii does not observe daylight saving time and remains on Hawaii-Aleutian Standard Time (which is equivalent to Yukon Standard Time).
Variants and Related Words
  • Alaska Standard Time (AKST): The contemporary common name for Yukon Time within Alaska.
  • Hawaii-Aleutian Standard Time (HST): The time zone observed in Hawaii, which is geographically and temporally equivalent to Yukon Standard Time (UTC-9).
